In late July 1897, General Longstreet became quite smitten with Helen Dortch. Various newspapers picked up on rumors that he was taking another bride, but he played coy with one persistent New York reporter before he finally confirmed the news.
"The General crossed his legs, looked out over the fields again, and replied: 'Oh, pshaw! Well, I suppose I might as well give in. I am to be married to Miss Dortch at noon on Wednesday in the Governor's residence in Atlanta. The honeymoon is to be spent in Porter Springs, where I hope you newspaper men will leave an old man to the happiness he has acquired."
On September 8, 1897, General Longstreet and Helen -- described on her wedding day as "pretty, piquant and sympathetic," with blue eyes, blond hair and fair skin -- exchanged vows in the parlor of the governor's mansion. It was reported in various newspapers that among those in attendance were the Gainesville mayor, a large group of Longstreet's friends and all of the General's five children. "They all warmly congratulated their new stepmother," one newspaper noted, "which should dispose of the story that there was any friction because of the marriage." Helen had picked the wedding date in honor of the General, who as an officer 50 years earlier, had heroically led his regiment at Molina Del Rey during the Mexican War.
Governor William Atkinson served as best man for General Longstreet during the Catholic ceremony. "When the officiating priest, after having asked the groom the question of assent, turned to Miss Dortch to know if she would take James as her husband," a newspaper reported, "it carried the suggestion to the groom's heart that he was a boy again, paddling in the Savannah River."
I really like this account and hope that it is true.
